ssl: only use the dummy cert hack if using an Apple Python (issue4410) The hack for using certificate store in addition to the provided CAs resides in Apple's OpenSSL. Apple's own Pythons will use it, but other custom built Pythons might use a custom built OpenSSL without that hack and will fail when exposed to the dummy cacert introduced in d7f7f1860f00. There do not seem to be a simple way to check from Python if we are using a patched OpenSSL or if it is an Apple OpenSSL. Instead, check if the Python executable resides in /usr/bin/python* or in /System/Library/Frameworks/Python.framework/ and assume that all Pythons found there will be native Pythons using the patched OpenSSL. Custom built Pythons will not get the benefit of using the CAs from the certificate store.

largefiles: move initialization of standins variable to clarify its "scope"

largefiles: the update override only needs lfdirstate and status for --check

largefiles: remove confusing rev parameter for lfdirstatestatus Dirstate only works on the repo wctx.

largefiles: replace repo._isaddremove hack with a simple function parameter

status: add more complete tests for --rev The 'status --rev' code is not very well tested, which has bitten us as recently as in issue4321. Let's add some more tests, some of which uncover bugs. Remove the few existing tests that are now covered in a more thorough and consistent way.
